Concanavalin A (Con A) was found to inhibit hexose uptake in cultured fibroblasts derived from 8-day chick embryos and to stimulate this process in those derived from 16-day embryos. Con-A effects… (More)

After treatment with trypsin, chick embryo fibroblasts exhibited an age-related difference in their capacity to readhere to the substratum, since 8-day-cells readhered more rapidly than 16-day-cells.… (More)

We have investigated the changes in glycosaminoglycan (GAG) composition between cultured fibroblasts derived from 8- and 16-day chick embryos. GAG composition has been studied after [3H]glucosamine… (More)

Concanavalin A (Con A) was utilized free, bound to Sepharose 4 B or cross-linked to glutaraldehyde to investigate the possibility of binding this lectin to radish beta-fructosidase (E.C.3.2.1.26).… (More)

Chicken serum contains 3 molecular species of immune-associated (Ia) antigen coded for by the major histocompatibility complex (MHC). These molecules are named B-L alloantigens [1]. They vary in… (More)
